The suitable water temperature range for koi is 18-28 degrees Celsius. Within this temperature range, koi are actively swimming, have a strong appetite, are in robust physical condition, and have vivid colors. Specifically:
Optimal growth water temperature: The most suitable growth water temperature for koi is 23-28 degrees Celsius. Within this temperature range, koi have the best growth and health status.
Suitable water temperature range: The growth water temperature for koi should be between 18-25 degrees. If the water temperature is lower than 15 degrees or higher than 30 degrees, it will affect the normal growth and health of koi.
Water temperature fluctuation: Koi have a strong adaptability to water temperature and can grow normally in water temperatures ranging from 5-30 degrees Celsius. However, sudden changes in water temperature will have an adverse impact on koi. Therefore, large fluctuations in water temperature should be avoided as much as possible.
In addition, the breeding of koi also needs to pay attention to water quality management, dissolved oxygen content, and the selection of feed to ensure their healthy growth.
